Serialization sizeWarningThreshold reached

Hi Chris, hi all, I'm testing my app with many objects by bulk loading it. When I do it for 1250 simple object transactions it works fine but when I start with the first of ten files with 42000 simple transactions by each I got this error so I "Proceed" and I got it again, and again. Finally a got Out of memory because Croquet.exe is about 500 mb of ram. All is working fine, process the file, creating all objects and adding to my application but the problem is when I do commit: to it. With this information could you guess what i'm doing wrong? Thanks in advance, FV p.s.: in my test i would like bulk load 42000 customers with 10 simple transactions by each. MaObjectSerializationWarning: Serialization sizeWarningThreshold reached.

getting up and running
by Daniel Lyons 17 Mar '11

Hi, I'm trying to get a Magma server up and running for the sake of learning, and having some trouble. My inclination is to use Pharo, but I'm getting the impression recent versions of Magma don't run on Pharo 1.1 or 1.2. Is there a known stable version of Magma that does that I can load? If so, how would I go about doing that? If the best answer is to use Squeak, I'm also a little confused about which package manager to use and how; the documentation on the Squeak wiki seems to be a bit out of date, or else I'm using too recent a version of Squeak (4.2 all-in-one). In short, I guess I'm wondering what versions of Magma run with what Smalltalks and how to get them there. I suspect I just have bad timing and this will all be sorted out soon, but I thought I'd check anyway just to see if there's something obvious I'm missing. Thanks! — Daniel Lyons
